“…Heat waves lead to sharp increases in mortality and respiratory emergency visits, as is well documented in many parts of the world, for example, in Spain (Diaz et al, ), Germany (Hermann & Sauerborn, ), China (Song et al, ), and the United States (e.g., Anderson et al, ; Vashishtha et al, ; Wang et al, ). Heat waves also affect agricultural productivity, including hen deaths which reduced egg production in Brazil (Lamarca et al, ), increases in female cattle mortality up to 40% in France (Morignat et al, ), lowered fertility in dairy cattle (Wolfenson & Roth, ), and reduced milk production in the United Kingdom and Australia (Chang‐Fung‐Martel et al, ; Fodor et al, ). Heat waves also stress ecosystems including temperate coastal Benthic communities (Pansch et al, ), affect the sperm quality of birds (Hurley et al, ), and induce complex responses of the biosphere (Flach et al, ).…”

This study examines the changing behavior of summer dry spell duration in response to increasing air temperatures at 517 Russian stations during 1966–2010. We found that the frequency distribution of dry spell duration (as represented by histograms) is becoming skewed toward longer dry spells. This asymmetrical shift is accompanied by mean increases in dry spell duration. This asymmetry is also reflected in exponentially higher increasing rates of dry spell duration toward higher percentiles. Consequently, across Russia, summers have experienced significant increases in 7‐day‐or‐longer dry spells (at 6.1%/°C of warming) and fewer occurrences of 3‐day‐or‐shorter dry spells (at 2.4%/°C). This study suggests that hotter summers favor more frequent prolonged dry spells, exacerbating drought and heat wave conditions during Russian summers as air temperatures continue to rise.

“…Pemanfaatan lahan pantai untuk lokasi peternakan unggas menjadi peluang yang sangat tinggi, namun banyak peternak yang tidak ingin mengambil peluang tersebut. Kondisi ini disebabkan oleh suhu lingkungan yang tinggi dengan fluktuasi panas (Lamarca et al, 2018) dan dingin secara ekstrim, akan menyebabkan penurunan produksi (Raharjo et al, 2018). Unggas memiliki sifat homeotermik sehingga akan mengalami penurunan konsumsi pakan dan produktifitas (Mascarenhas et al, 2018) jika kondisi lingkungan memiliki panas yang sangat tinggi.…”

Salah satu kendala pemanfaatan lahan pantai untuk budidaya ternak ayam petelur adalah suhu lingkungan yang tinggi dengan adanya fluktuasi panas dan dingin secara ekstrim, sehingga menyebabkan rendahnya konsumsi pakan dan produktifitas. Penelitian ini bertujuan untuk menyusun formulasi ransum padat nutrisi dengan baku baku distiller dried grains with soluble (DDGS) dengan pakan dalam bentuk crumble. Penelitian ini dilakukan di daerah pantai dengan menggunakan DDGS 10% (P1), DDGS 30% (P2) dan DDGS 30% dan methionine 1.0% (P3). Ayam yang digunakan adalah Layer sebanyak 180 ekor berumur 18 bulan pada peternakan milik Bapak Sarju dengan 3 perlakuan dan 3 ulangan. Hasil penelitian menunjukkan bahwa HDA dan konversi pakan menunjukkan perbedaan yang sangat nyata (P<0.01) secara berturut-turut yaitu 78.62%; 85.07% dan 89.53% dan 2.45%; 2.33% dan 2.00%. Perbedaan yang nyata (P<0.05) pada rata-rata berat telur yaitu 63.00; 64.25; dan 70.75 Dapat disimpulkan bahwa DDGS dapat digunakan sebagai bahan pakan hingga 30%, akan meningkatkan produksi telur di Lahan Pantai jika ditambahkan methionine.

“…especially, ambient temperature is being widely recognized as a main stress factor (Lin et al 2006;Singh et al 2017;Vandana et al 2021). It seems highly realistic that free-range farming may also face problems associated with local manifestations of climate change, especially the extension of the warm period not only in geographic areas affected by high environmental temperatures but also in Europe (Alexandrov et al 2002;Lamarca et al 2018).…”

This trial studied the influence of environmental conditions (cold, thermoneutral and hot period) on oxidative status of different genotypes free-range laying hens and the effect of oxidative stress (OS) on their egg productive performance. In the experiment, carried with a two-year replication, were used six dual-purpose chicken genotypes with different origins. For determination of the oxidative status were measured the levels of lipid peroxidation (LPO), total glutathione (tGSH) and the activity of antioxidant enzymes catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPX). The highest egg production for all chicken genotypes was reported during the thermoneutral period. Biochemical parameters LPO and CAT were relatively more sensitive to environmental impact while the remaining (tGSH, SOD, GPX) exhibited a higher degree of stability. The lowest values of LPO for all genotypes were proved during the thermoneutral period. The cold period was most unfavorable – LPO values are elevated for all genotypes. The SOD and GPX values were higher during the cold and the hot periods compared to the thermoneutral. The results of analysis of variance showed that the factor “temperature period” compared to “year” and “genotype” had the most significant influence on all biochemical parameters (P<0.001). Significant phenotypic correlations (P<0.05) were detected among all biochemical parameters, except for correlation between SOD and tGSH. The chicken genotypes showed differences in their susceptibility to OS. Thermal stress (either cold or heat) affected adversely the oxidative status of hens because it induces OS and can play a significant role in determining chicken welfare and egg production.
